Supported values for address_family are currently AF_INET and AF_INET6. If the IP address string ip_string is invalid, OSError will be raised. Note that exactly what is valid depends on both the value of address_family

class email.charset.Charset(input_charset=DEFAULT_CHARSET) Map character sets to their email properties. This class provides information about the requirements imposed on email for a specific character set.
